Rotating disk alumina precursor fiber formation process stability determination using image analysis
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Precursor fibers are made from the aluminium-hydroxide chloride based sols. The process stability can be influenced both by the fiber formation conditions and the rheology of the sol. The distance from the disk canter is ...
The effect of mould temperature and cooling conditions on the size of secondary dendrite arm spacing in Al-7Si-3Cu alloy
(Savez inženjera metalurgije Srbije, Beograd, 2009)
The secondary dendrite arm spacing (SDAS) is one of the most important microstructure features of as-cast structure in hypoeutectic aluminum alloys. The size of SDAS depends on many factors such as liquid metal treatment, ...
A case study of global steel properties database development: Key to steel / Primer razvoja globalne baze podataka osobina čelika - key to steel
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Key to Steel is the world’s most comprehensive database of steel materials developed to provide technical information to professional users worldwide. This paper describes development process that resulted in the biggest ...
FEM modeling of dynamic recrystallization in 304 stainless steel
(Savez inženjera metalurgije Srbije, Beograd, 2005)
Series of isothermal uniaxial compression tests in the temperature range (600-1100°C) with two strain rates of 0.1 and 1.0 s"1 were performed with the aim to obtain input data for the finite elements modeling (FEM) of ...
Possibilities of recycling of magnesium and magnesium alloys
(Savez inženjera metalurgije Srbije, Beograd, 2004)
In this paper are presented results of experimental investigation of processing of non oil-contaminated metal scrap based on magnesium and its alloys. These are the firs investigations of magnesium scrap recycling in Serbia ...
Characterization of wastewater streams from Bor site
(Savez inženjera metalurgije Srbije, Beograd, 2007)
This paper presents full characterization of wastewater streams within Bor copper mine. Seven different wastewater streams were identified and fully characterized (origin, flow rate, chemical and physical properties) on ...
An improved method for thermal stability behavior characterization of silicon carbide/cordierite composite material
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950°C, ...
Kinetics of crystallization silicon-(IV)-nitride / Kinetika kristalizacije silicijum-(IV)-nitrida
(Savez inženjera metalurgije Srbije, Beograd, 2003)
Amorphous covalent Si-C-N ceramics have been synthesized by pyrolysis polysilazanes. This part of experiment was done in Institute für Nichtmetallische Anorganische Materialien, Universitaet Stuttgart, Germany. Ceramics ...
Development of a collision energy absorber of a passenger train
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Development of shock absorbers is one of the necessary measures for passive protection of passenger coaches. The purpose of passive protection is to minimize the collision consequences for passengers. Present solutions are ...
Determination of activation energy for static recrystallization using multipass continuous cooling torsion test
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Two microalloyed steels (Nb low carbon and V medium carbon) were tested by means of multistage continuous cooling torsion with aim to evaluate the interpass recrystallization data, by means of Tnr (temperature of ...
